Coin task rendering should show product details

Right now build results page on testresults.qt.io displays sha1's of all built modules, however it doesn't specify sha1 of qt5 that was used as a base. It can only be found in windows build logs after "Project:qt/qt5 Sha1:"

More generally speaking, with a more flexible product structure, it really makes sense to show details about the product a build was done against (or list of products even).

This should be fairly easy to implement in the front-end given that the data structures should have the information.
